Research Summary

Michelle's lab develops innovative approaches to discover chemical tools and drug leads to demonstrate 'druggability' of new target classes and to discover new targets for drug discovery. Areas of interest include protein-protein interactions, allosteric and scaffolding sites in enzymes, and orphan and neglected diseases. Michelle is Director of the Small Molecule Discovery Center, a collaborative research facility that includes high-throughput screening and medicinal chemistry (smdc.ucsf.edu). The SMDC is a Cancer Center Core.
